Things from Cultured Code also comes as an iPhone app, and the duo update each other fairly well. They miss out on being being “excellent” because the iPhone-to-mac syncing only happens when both your devices are on the same wifi network, and short of closing one of the pair and re-opening it, I can’t fnd a way of forcing a sync to happen whenever you would like.

That being said, they do both work extremely well. The desktop version has a very nice quick-entry interface which feels a little bit like Quicksilver (and is accessed by pressing Ctrl+Alt+Space) which is a nice touch. Both apps use “dock badge” numbers although the number shown can only be customised on the desktop version which lets you set the number as Due, Due+Today and Due+Today+Inbox; the iPhone dock badge will only show Due+Today so personally although I would like the full count I leave the setting so that both are the same.

Neither app is free. The desktop client is (at the current exchange rate) £37.13 ($49.95) and you can buy Things from the App Store for £5.99 ($7.99). The desktop version is also available as a 5-license bundle for £55.72 ($74.95)
